Dutch men are holding hands in an act of protest and solidarity after a gay couple was brutally beaten for holding hands in public.

Jasper Vernes-Sewratan and Ronnie Sewratan-Verne were holding hands in Arnhem, Netherlands, when they were attacked by a group in the early hours of Sunday morning.

Vernes-Sewratan told Dutch broadcaster NOS that they don't usually hold hands in public because they "don't want to provoke people."

"But we’d had a nice evening, it was late and we thought we were alone," he said.

"Before I knew it I was on the ground fighting with three men on top of me," Vernes-Sewratan continued.

The attack prompted widespread outrage in the Netherlands, and Dutch journalist Barbara Berend called on men to hold hands in solidarity with Vernes-Sewratan and Sewratan-Verne and to share photos using the #allemannenhandinhand (#allmenhandinhand) hashtag.
